1 Claim. (Cl. 72-101) an antenna mast upon a chimney but, so far as I amaware, all such prior devices have been applied to the chimney aftererection of the same and hence when the mortar between the bricks hashardened, as disclosed for instance in the patents to Wicke, No.1,691,864, November 13, 1928, Sadler, No. 1,745,814, February 4, 1930,

and Cohn, No. 2,482,575, September 20, 1949.

Accordingly, the object of my present invention is to provide animproved device for mounting a mast, which may be set in the wet mortarbetween the bricks of a chimney while it is being constructed so that mymount- .ing device becomes an original and permanent part of thechimney, and which may be of a comparatively simple and inexpensivestructure.

More specifically, the object of my present invention is to provide sucha device which comprises a pair of duplicate members each of which is ofone-piece or integral form and is of suitable dimensions for placingbetween the ends of the bricks and is provided with means whereby thewet mortar and the member may become set and bonded together as aunitary combination at the time of erecting the chimney.

Other objects will appear from the following description and claim whenconsidered together with the accompanying drawing.

Fig. 1 is a perspective view illustrating my present invention installedin a brick chimney;

Fig. 2 shows in elevation one of the members of my present improvement;

Fig. 3 is a plan view of the same;

Fig. 4 is an end view thereof; and

Fig. 5 is a detail view taken on line 5-5 of Fig. 3.

It is to be understood that the present form of disclosure is merely forthe purpose of illustration and that there might be devised variousmodifications thereof without departing from the spirit of my inventionas herein set forth and claimed.

Referring now to the accompanying drawing in detail, there isillustrated a conventional form and construction of brick chimney inwhich the bricks B are of usual dimensions. Since my presentmast-supporting device itself consists of duplicate members, a detaileddescription of one of these members will no doubt suflice with theexplanation that these two members are arranged in vertical alignment,as indicated in Fig. l of the present drawing.

Each of these two members has its integral outer end tending in avertical plane and may be of substantially the same dimensions as theend of the conventional brick B. The flat portion 3 may be ofsubstantially uniform thickness throughout and is of less thickness thanthat of the mortar between the bricks B'of the chimney so as to permitthe same to be placed between the bricks while the chimney is beingerected and to become bonded together with the mortar as it sets; and,in order to still further promote this bonding engagement, the flatportion 3 is provided with a plurality of triangularly arrangedapertures 4 to receive the mortar therein and therethrough.

As indicated above, each of these two duplicate members will be set inposition between the ends of adjacent bricks B as the chimney is beingerected and they will be placed in vertical alignment and at properdistance apart so as to receive and hold the mast M in vertical positionin the apertures of the portions 1. Also, these two duplicate memberswill be of suitable length to permit the mast M to clear any coping thatmay be provided upon the top edge of the chimney; in any event, theremay be allowed suitable spacing of the mast M from the chimney and thesemembers may be given a length accordingly.

The intermediate portion 5 of each of these two duplicate members is offlat form extending in the same vertical plane as the inner portion 3;and the intermediate portion 5 may be provided with the reinforcing ribs6 along the upper and lower edges thereof.

Thus each one of these duplicate members is made of one piece, with theportions 3 and 5 extending in the same vertical plane and with theapertured or hollow portion 1 also extending vertically. That is to say,the hollow outer end portion 1 may be recognized as a continuation ofthe vertically disposed portions 3 and 5, thereby simplifying theconstruction of these members and also contributing to their supportingstrength in a most effective manner since they are disposed upon edgeand thus there is no danger of their failure in supporting the load ofthe antenna mast. The ribs 6 ensure against any danger of yielding ofthese members in a lateral direction.

By making the flat portion 3 of suitable thickness, having in mind theconventional space between two bricks in a chimney, there may be aneffective film of mortar between each face of the portion 3 and theadjacent brick and these two opposite films of mortar will be joined bythe intermediate portions of mortar which fill the apertures 4 so "as toproduce a most eifective bond for holding the member securely in placebetween the bricks.

With my present form of mast-supporting device, it becomes an originalpart of the chimney construction and thus there may be avoided thedifiiculty of later providing such a mast-supporting means after thechimney has been erected and the mortar hardened. Therefore my presentinvention makes it possible to realize a decided saving in trouble andexpense and also to enjoy an increased efliciency and dependability.Because of the comparatively low cost of the members included in mypresent invention, it becomes practically expedient to install them asan original part of the chimney so as to have them ready for use at oncewhenever desired.

What I claim is:

In combination, a wall of bricks with staggered joints and with mortarin the joints, and a mounting device for a mast comprising a pluralityof duplicate members in vertical alignment, each of said members havingits outer end formed with a vertically disposed opening to receive themast and provided with means for securing the same therewithin, each ofsaid members having its inner end portion formed as a flat web of thesame height as that of a brick and extending in a vertical plane, saidweb being of less thickness than that of the mortar between the bricksand being set between the ends of adjacent Patented Apr. 22, 1958 v j"2,831,339 1 V 23 l, 4
